Test Case: Extended Inode Decoding

Test ID: TC023-extended-inode-normal

Objective

Verify a real 64-byte extended regular inode, including size, full-width metadata, timestamps, and source-exact content.

Fixture

Use images/extended.erofs and source/extended/large-file.bin. fixture-evidence.txt records the NID, byte offset, size, and inode_size=64.

Procedure

stat -f 'ino=%i size=%z mode=%p nlink=%l mtime=%m ctime=%c blocks=%b' "$mnt/large-file.bin"
cmp /tmp/repo22-g1/source/extended/large-file.bin "$mnt/large-file.bin"
sha256 /tmp/repo22-g1/source/extended/large-file.bin "$mnt/large-file.bin"

Expected Results

• The file reports the evidence/source size, regular 0644, link count 1, deterministic timestamps, and a 64-byte on-disk inode.
• Full source compare and SHA256 match; cleanup succeeds.
